Question

Here's my holiday h.w Maths question-
Cutting a circle into equal sections of a small central angle to find the area of the circle by using the formula A = pie*(r)square. Give explanation of how you did it.
Please explain me in a precise way.

Answer 1

Answer:

This is one of our icse math project topics right?? Well our teacher explained it to us..first we need to draw a huge circle on a chart paper with unknown radius.Then we need to cut out equal sections of the circle just like how u cut a pizza slice.When u have cut out the whole circle, place each section next to each other by alternately placing in opposite direction.Now u'll get a line of these sections.Measure the length of it and this gives u the circumference of the circle.Now from the circumference u can find the radius of the circle using the formula 2r. From the resulting radius u can easily find out the area of the circle using the formula .
